According to Wikipedia, Shimon Peres was born on Aug. 2, 1923. But try telling that to him.
Peres had an eventful year leading up to his 89th birthday. In 2012, the president of Israel starred in YouTube viral video effort as part of a social media campaign to promote his Facebook page. He was also awarded the Presidential Medal of Freedom by U.S. President Barack Obama.
Greer Fay Cashman has written for the Jerusalem Post that Peres typically celebrates his birthday on August 16. In 1988, for example, Peres celebrated his 65th birthday with Jerusalem mayor Teddy Kollek on that date. But according to Cashman, the August 2 date was actually retrofitted to the Hebrew date the 20 of Av.
Prior to his assumption of the presidency, biographical data gave August 16 as his date of birth. The change occurred after he decided that from a personal standpoint, he would celebrate his birthday according to the Hebrew calendar date of Av 20, which in 1923, the year of his birth, coincided with August 2.
Add that to the list of things you didn’t know about Shimon Peres.
